Environmental and Food Sciences

Recently, environmental science has become one of the fastest growing life science disciplines.
The dramatic attention originates from a continuous search for answers to global challenges, such as climate change, water and air quality and pollution monitoring.
  • Electron microscopy has been an irreplaceable tool for studying many environmental systems.
  • TESCAN SEMs portfolio covers a variety of instruments and analytical solutions for analysing pollution particles, water and soil organisms, minerals, rocks, crops, and many more.
  • Advancement in Food Science and technology are another highly demanded area of today’s science community. Developing specialized crops, studying pesticide resistance and production of nutritious and less cost food supplies are critical scientific topics in a today’s populated world.
  • With TESCAN SEM technology, researchers can easily study different products at a wide range of magnification and high resolution. By using UniVac and the Water Vapor Inlet system, all environmental samples can be studied close to their natural state, thus further improving technological processes and crop formulations.

Low temperature scanning electron microscopy for Life Sciences
Low temperature scanning electron microscopy (Cryo-SEM) has become an established technique for capturing and observing biological samples close to their natural state. It is a method of choice, where the traditional sample preparation (e.g. critical point drying) causes unwanted changes in the sample structure. A Cryo-SEM workflow typically involves sample fixation using either flash-freezing in a liquid nitrogen slush or high-pressure freezing. The frozen samples are then transferred under vacuum to a cryo sputter coater, where they are coated with a conductive layer of metals or carbon. Finally, the samples are inserted into a SEM chamber equipped with a cryo-stage and observed in high vacuum environment.
